TECHNICAL FIELD

The present disclosure relates to bearing flushing compositions and methods of flushing bearings and bearing assembly housings, particularly flushing used grease from bearing assemblies of rotating equipment and industrial machinery.

BACKGROUND

Bearings may be used to support rotating components in various household and industrial environments. Wind turbine generators, for example, employ bearings to support rotation of a main shaft. Lubricants may also be used to reduce friction and thermal build-up. The most common lubricant used in main bearings of wind turbine generators is grease which has the advantage of being easily retained in the bearing arrangement and contributes to sealing the bearing arrangement from contamination.

Over time grease decomposition products, concentration of grease thickeners, collection of wear debris, and dirt and dust accumulation in the in-service grease because of operation of the equipment, equipment wear, heating of the grease and contact with the atmosphere causing the grease to thicken, increase in viscosity, and harden into sludge. An accumulation of this hardened grease will eventually cause the bearing to overheat, exhibit decreased efficiency, and ultimately fail.

To properly maintain the bearing, hardened grease that has accumulated on the bearing and bearing housing must be periodically removed from the bearing and bearing housing and replaced with fresh grease.

SUMMARY

In one aspect, a bearing flushing composition includes a grease component and a solvent component. The grease component may include a grease thickener component, a base oil component, and, optionally, a performance additive component. The solvent component may include one or more solvent agents blended with the grease component.

In one example, the composition may include approximately 3% to approximately 20% by weight solvent component. In a further example of the above example or in another example, the composition may include approximately 80% to approximately 97% grease component. In still a further example of an above example or in another example, the grease component may include approximately 1% to approximately 10% performance additive component.

In still a further example of an above example or in another example, the solvent component may include one or more solvent agents solubilized in the grease component. In still yet a further example of an above example or in another example, the solvent component is solubilized into the grease component.

In another aspect, a method of flushing a bearing assembly includes introducing a bearing flushing composition into a bearing assembly housing comprising a bearing and introducing a replacement grease into the bearing assembly housing.

BRIEF DESCRIPTION OF THE DRAWINGS

Various features and characteristics of the non-limiting and non-exhaustive embodiments disclosed and described in this specification may be better understood by reference to the accompanying figures, in which:

FIGS. 1A-1D schematically illustrate a method of flushing a bearing assembly according to various embodiments.

DESCRIPTION

When grease in bearings degrades and hardens, it is no longer useful as lubricant, which can lead to overheating, bearings lock-up, and downtime on the piece of equipment with locked bearings. To combat such undesirable outcomes, the old, in service grease is preferably removed from the bearing and replaced before equipment failure occurs. However, the difficulty in replacing the grease lies in removal of the depleted and contaminated grease to be replaced from the bearing. For example, the rotating equipment in which the bearing services may be required to be taken offline for grease changeout, which may also include removing or exposing bearings to gain access to the bearings for cleaning. Incomplete removal of the old, in service grease can contaminate the new grease and reduce its lubricant properties as well as its operational life. According to various embodiments, the present disclosure describes compositions and methods for flushing old, in service grease, which may include accumulated hardened grease, sludge, and debris, from bearing assemblies such as bearings and bearing assembly housings of rotating equipment and industrial machinery.

In some embodiments, the compositions and methods may be employed for cleaning a bearing in rotating equipment and industrial machinery that includes flushing the bearing and bearing assembly housing of accumulated hardened grease, sludge, and debris, thereby enabling a user to clean and then re-lubricate the bearing. For example, in some embodiments, the compositions and methods may be utilized to flush old, in service grease from bearings and bearing assembly housings of rotating equipment and industrial machinery while the equipment or machinery remains on-line. In the above or another embodiment, the compositions and methods may be utilized to flush old, in service grease from assembled bearings and bearing assembly housings of rotating equipment and industrial machinery, e.g., without requirement for disassembling the bearings in order to clean them.

In various embodiments, one or more of the grease thickener component, fluid base oil component, additive component, or agents thereof may be selected from those specified for the bearings and bearing assembly housings of the particular grease application at hand. For example, the grease component may include the same or similar grease thickener, fluid base oil, additives, or combinations thereof as the grease it is used to flush. In the above or another example, the weight ratio of one or more of the grease thickener, fluid base oil, or additives in the grease component may be the same or similar to that of the grease it is used to flush.

As introduced above, the bearing flushing composition may include a solvent component. The solvent component may include one or more solvents. In various embodiments, the solvent component may include at least one solvent selected from oil soluble polyalkylene glycols, synthetic esters, terpenes, alkylbenzenes, alkyl naphthalenes, mineral oils, polyalphaolefin oils, or combinations thereof. In one embodiment, all or a portion of the solvent component may be solubilized within the grease thickener component. According to various embodiments, the solvent component or one or more solvents thereof may be utilized to particularly solubilize the grease thickener component or agents thereof and old, in-service grease to be removed, such as decomposed grease, allowing it to be flushed from a bearing. In so doing, the bearing may be cleaned of old hardened grease providing the operator a method to replace this flushing grease by normal purging methods without requiring dismantling of bearing assembly housings for cleaning.

In one example, the bearing flushing agent includes approximately 75% to approximately 85% grease component and approximately 25% to approximately 15% solvent component wherein the grease component comprises a calcium sulfonate complex grease and the solvent component comprises an oil soluble polyalkylene glycol.

In various embodiments, the grease component comprises an overbased calcium sulfonate complex grease and the solvent component comprises an oil soluble polyalkylene glycol. In the above or another embodiment, the overbased calcium sulfonate complex grease comprises from approximately 10% to approximately 20% by weight high viscosity polyalphaolefin oil.

As introduced above, the bearing flushing composition may include a grease component and a solvent component, which may be blended into the grease component. According to various embodiments, a method of making the bearing flushing agent may include combining the grease component and solvent component and mixing to formulate a blended mixture. In some such or other embodiments, the solvent component or one or more solvents thereof may be solubilized into the grease component or one or more components thereof.

In one embodiment, the grease component, or one or more components or agents thereof, may be heated and combined with the solvent component, or one or more solvents thereof, which may also be heated. The combined ingredients may then be mixed to formulate a blended mixture. In one example of the method, a drum mixer may be charged with grease component and agitated. Heated solvent may then be added and the resultant mixture stirred to form a blended mixture. Duration of stirring may depend on the identities and amounts of the components being mixed, but generally stirring times may be undertaken for about 2 hours or at least 2 hours. For example, stirring may be undertaken for about 2.5 hours, 3 hours, 3.5 hours, 4 hours, or more. However, in some formulations lesser times may be appropriate. The blended mixture may then be used or packaged in suitable containers and stored.

A method of making a bearing flushing composition comprising approximately an 80:20 grease component to solvent component weight ration may include charging approximately 80 weight percent of a heated grease to a drum mixer and starting agitation. Approximately 20 weight percent of heated solvent, such as oil soluble polyalkylene glycol may be added to the drum. The resultant mixture may then be stirred for at least 2 hours prior to storage or packaging. While the bearing flushing composition is generally described as being formulated by mixing the grease component with the solvent component, it will be appreciated that is some embodiments the various components may be premixed or mixed in other orders. For example, an additive component or agent thereof could be premixed with all or a portion of one or more of the fluid base oil component, grease thickener component, or solvent component.

In various embodiments, the bearing flushing compositions disclosed herein generally comprises grease compositions formulated to be pumped into a bearing assembly housing to soften and flush the bearing and bearing assembly housing of old, in-service grease. For example, a method of flushing a bearing assembly, which may comprise a bearing and bearing assembly housing, may include forcing or pumping the bearing flushing composition into a bearing assembly housing. The method may also include purging the flushed depleted and contaminated grease from the bearing assembly housing and introducing, e.g., by forcing or pumping, fresh compatible grease into the bearing assembly housing to lubricate the bearing.

While various bearing systems are suitable for use with the bearing flushing compositions and methods of flushing bearings and bearing assembly housings disclosed herein, a preferred system is equipped with a grease Zerk fitting or other similarly effective inlet for introducing the bearing flushing composition into the bearing under pressure. As such, introduction of the bearing flushing composition into the bearing assembly housing may displace the contaminated grease present in the bearing. One preferred tool for use in forcing the bearing flushing composition into a bearing is a handheld grease gun having a hose with a fitting on the free end that is attachable to a grease Zerk fitting. Such handheld grease guns are known in the art and may utilize a handle-driven piston to expel the bearing flushing composition from an elongated cylindrical package into the hose and from the hose, through the grease Zerk fitting, and into the bearing system.

FIGS. 1A-1D, schematically illustrate a method of flushing a bearing assembly 10 according to various embodiments. The bearing assembly 10 may include a bearing assembly housing 12 that houses a bearing 14 (shown in ghost) within an interior portion 16 of the bearing assembly housing 12. The bearing assembly 10 may support a rotatable shaft 18 or other rotatable equipment or industrial machinery that extends through the interior portion 16 of the bearing assembly housing 12. The bearing assembly 10 may include a ports 20, 22 operable as a grease inlet 20 and a grease outlet 22 in fluid communication with the interior portion 16 of the bearing assembly housing 12. As noted above, the grease inlet 20 and grease outlet 22 may include Zerk type fittings.

With specific reference to FIG. 1A, the grease lubricant 30 may be contained in the interior portion 16 to lubricate and protect the bearing 14 during rotation of the shaft 18. In some embodiments, the bearing assembly 10 may remain in service and operate throughout the flushing process. For example, the shaft 18 may be operatively rotating throughout the flushing process, as generally indicated by arrow R. According to various embodiments, a method of flushing the bearing assembly 12 of the grease lubricant 30, such as when the grease lubricant has deteriorated or become contaminated through use, may include introducing a bearing flushing composition 32 comprising a grease component and a solvent component as described herein into the interior portion 16.

As depicted in FIG. 1B, the bearing lubricant composition 32 may be introduced into the interior portion 16 of the bearing assembly housing 12 through grease inlet 20. Introducing the bearing flushing composition may include injecting the bearing flushing composition into the interior portion 16, e.g., with a grease gun or pump. Introducing the bearing flushing composition 32 into the interior portion 16 of the bearing assembly housing 16 may result in displacement and flushing of all or a portion, such as a significant portion, of the old grease from the interior portion 16 through the grease outlet 22.

With specific reference to FIG. 1C, once the bearing flushing composition 32 has displaced and flushed all, a portion, such as a significant portion, of the old contaminated grease from the interior portion 16 of the bearing assembly housing 12 the bearing 14 may be run for a run period, e.g., the shaft 18 may remain in service. The run period is preferably at least approximately 4 hours, and preferably from approximately 4 to approximately 8 hours for main shaft bearings of wind turbines; however, longer or short run periods may be used, for example, based on the amount of cleaning desired. During the run period, the bearing flushing composition 32 breaks down buildup, contaminants, hardened grease deposits, a collects debris to clean the bearing 14 and bearing assembly housing 12. In some examples, performance additives, such as polishing agents, may interact with contaminants remaining within the interior portion 16 of the bearing assembly housing 12 thereby loosening or abrading the contaminants from metal surfaces inside the bearing assembly housing 12, which may then become suspended in the bearing flushing composition 32.

To maximize cleaning effectiveness, additional bearing flushing composition 32 (not shown) may optionally be introduced into the bearing assembly 10 system at one or more points during the run period. For example, additional bearing cleaning composition 32 may be injected approximately halfway through the run period to flush out deposits displaced up to that point in the cleaning cycle.

With specific reference to FIG. 1D, the method may also include flushing the bearing flushing composition 32. For example, at the end of the run period, the method may include flushing the used bearing flushing composition 32′ from the bearing assembly 10. For example, re-lubricating grease 32 may be introduced via grease inlet 20 to displace the used bearing flushing composition 32′ from grease outlet 22. In various embodiments, the re-lubricating grease 32 may be introduced with the bearing 14 still in operation to flush the bearing flushing composition 32′ from the interior portion 16 of the bearing assembly housing 12. The re-lubricating grease 34 will typically be clean grease of the type normally used during regular service. Injection of the re-lubricating grease 34 may be continued until the used bearing flushing composition 32′ is no longer being expelled from the bearing assembly 10, e.g., from grease outlet 22. As with all greases, care should be taken to avoid contamination of fresh supplies of the bearing cleaning composition when not in use. The amounts and percent compositions described herein with respect to the bearing flushing composition, components, and agents thereof are intended to be applicable to any combination of amounts or percent composition described herein with respect to the bearing flushing composition, components, or agents thereof consistent with this disclosure. Similarly, it will be appreciated that the bearing flushing composition may include any combination of the various components and agents identified herein consistent with this disclosure. Other alterations and modifications of the invention will likewise become apparent to those of ordinary skill in the art upon reading this specification, and it is intended that the scope of the invention disclosed herein be limited only by the broadest interpretation of the appended claims to which the inventors are legally entitled.
